Do you mean that it isn't using the 'nearest' filter with the OpenGL2 renderer?
from python-tcod.
If it's just the filter then you should be able to affect it with an SDL hint:
import tcod
tcod.lib.SDL_SetHint(b"SDL_RENDER_SCALE_QUALITY", b"0")
Calling this before creating the context will enforce the nearest filter no matter which renderer you use.

Integer scale only refers to the output resolution, not the upscale filter that's used. Being able to change the filter of the OpenGL 2 renderer is a recent feature. The OpenGL 1 renderer is limited to using the nearest filter only. I'm not sure if the nearest filter is the default for SDL2 in all cases.
The preferred filter depends on the tileset and the desired aesthetic. The SDL hint is something I could document better.

I remember that image scale solved the blurry graphics
Integer scaling, not image scaling. It prevents sub-pixel distortion, which could appear as a blurry smear with a linear filter, or as jagged non-square-pixel artifacts with a nearest filter. Integer scaling ensures that the tileset doesn't get distorted, but doesn't determine if the tileset will be pixelated or smooth when upscaled.

It worked perfectly. Thanks!
